The High Resolution Dynamics Limb Sounder (HIRDLS) aboard the EOS Aura spacecraft (launched July 15, 2004) measures infrared emissions in 21 channels ranging from 6.12 to 17.76 microns. These measurements are used to derive vertical profiles of Ozone, HNO3, Water Vapor, Methane, N2O, NO2, N2O5, CFC11, CFC12, aerosols, and atmospheric temperature, as well as the locations of polar stratospheric clouds and cloud tops. At this time, only Ozone (O3) , Nitric acid (HNO3), CFC-11, CFC-12, Aerosol Extinction (12.1 micron), Temperature, and Cloud Top Pressure are available
HIRDLS V003 Level-2 daily data product contains vertical profiles of Ozone (O3), Nitric Acid (HNO3) and Temperature, as well as Cloud Top Pressure at spatial resolution of about 100 km along orbit track. This product (HIRDLS2.003) is based on the HIRDLS v2.04.09 algorithm.
HIRDLS V004 Level-2 daily data product contains vertical profiles of Ozone (O3), Nitric Acid (HNO3), CFC-11, CFC-12, Aerosol Extinction (12.1 micron) and Temperature, as well as Cloud Top Pressure at spatial resolution of about 100 km along orbit track. This product (HIRDLS2.004) is based on the HIRDLS v2.04.19 algorithm.
